instruct the conveyor to transfer the first item to the first item cubby when the sorting platform is aligned with the first item cubby.

2. The inventory handling system of claim 1 , wherein the mobile drive unit is configured to engage with and transport the storage unit and the management module is further operable to instruct the mobile drive unit to engage with and transport the storage unit when the first item is received in the first item cubby.

3. The inventory handling system of claim 1 , wherein the sorting platform comprises a transfer device operable to convey the first item to the first shelf.

4. The inventory handling system of claim 1 , wherein the management module is further operable to:

instruct the sorting platform to transport a second item of the one or more items along the height of the set of vertical support structures to a position for transferring the second item to a second shelf of the shelves based on second order data associated with the second item;

instruct the sorting platform to transfer the second item to the second shelf; and

instruct the mobile drive unit to position the mobile sorting assembly adjacent to the storage unit and align the second shelf with a second item cubby of the plurality of item cubbies.

5. A management module operable to instruct a system to:

instruct a first mobile sort assembly comprising a sorting platform and a plurality of sorting shelves positioned on a base to move a first item positioned on the sorting platform along a height of the first mobile sort assembly to a first sorting shelf selected from the plurality of sorting shelves;

instruct a first conveyance mechanism coupled with the first sorting shelf to transfer the first item from the sorting platform to a position on the first sorting shelf;

instruct a first mobile drive unit to engage with the base of the first mobile sort assembly and move the first mobile sort assembly to align the first sorting shelf with a first item cubby of an inventory holder; and

instruct the first sorting shelf to transfer the first item to the first item cubby.

6. The management module of claim 5 , wherein the management module is further operable to instruct the first mobile drive unit to engage with the inventory holder and move the inventory holder when the first item has been received in the first item cubby.

7. The management module of claim 5 , wherein the management module is further operable to instruct a singulation device, upon receiving a plurality of items, to position the items one at a time on a conveyance mechanism, and to convey the items to a position for transferring of the first item to the sorting platform.

8. The management module of claim 5 , wherein the management module is further operable to instruct a second mobile sort assembly to move a second item positioned on a sorting platform along a height of the second mobile sort assembly to a second sorting shelf selected from the plurality of sorting shelves;

instruct the sorting platform to transfer the second item to the second sorting shelf; and

instruct a second mobile drive unit to move the second mobile sort assembly to a position where the second sorting shelf is aligned with a second item cubby.

9. The management module of claim 8 , wherein the second item cubby is positioned within an internal volume of the first item cubby, the internal volume defined by walls.

10. The management module of claim 5 , wherein the management module instructing the system to transfer the first item from the sorting platform to a position on the first sorting shelf comprises the management module instructing the system to operate a second conveyance mechanism coupled with the sorting platform to convey a portion of the first item to an edge of the sorting platform.

11. A method comprising:

moving a sort platform along a height of a first mobile sort assembly with a first item positioned thereon to a first sorting shelf selected from a plurality of sorting shelves based on order data associated with the first item;

conveying the first item to the first sorting shelf;

moving, via a mobile drive unit, the first mobile sort assembly to a position where the first sorting shelf is aligned with a first item cubby; and

conveying the first item from the first sorting shelf.

12. The method of claim 11 , further comprising conveying the first item into the first item cubby positioned within an inventory holding device.

13. The method of claim 12 , further comprising moving the first mobile sort assembly to a position where the first sorting shelf is aligned with a second item cubby.

14. The method of claim 11 , further comprising:

moving the sort platform along a height of the first mobile sort assembly with a second item positioned thereon to the first sorting shelf;

conveying the second item to the first sorting shelf;

moving, via the mobile drive unit, the first mobile sort assembly to a position where the first sorting shelf is aligned with the first item cubby; and

conveying the second item from the first sorting shelf.

15. The method of claim 11 , further comprising:

receiving a second item on the sort platform;

moving the sort platform along the height of the first mobile sort assembly with the second item positioned thereon to a second sorting shelf selected from the plurality of sorting shelves;

conveying the second item to the second sorting shelf;

moving, via the mobile drive unit, the first mobile sort assembly to a position where the second sorting shelf is aligned with a second item cubby; and

conveying the second item from the second sorting shelf.

16. The method of claim 11 , wherein conveying the first item to the first sorting shelf comprises operating a conveyance device coupled with the sort platform.

17. The method of claim 11 , wherein conveying the first item from the first sorting shelf comprises operating a conveyance device coupled with the first sorting shelf.
